I’m having a strange issue when I activate Advanced Custom Fields that causes a server error when I try to access the taxonomy and user settings pages. When it’s deactivated, the pages work.
Pages in question
http://exampledomain.com/wp-admin/user-edit.php?user_id=###
http://exampledomain.com//wp-admin/edit-tags.php?taxonomy=category or any custom tax I’ve created
Any ideas why this may happen?
Hi @unwrittendevin
Are you able to turn on DEBUG MODE in your wp-config.php file and reload the page. Is any error message shown?
It is possible that the error is caused by the page taking too long to load. What if any fields have you added to the user / taxonomy page?
Thanks

Hi @unwrittendevin
Are you able to deactivate all other plugins / change to default theme.
I understand that ACF is causing the issue, but perhaps it is not the root of the problem. Perhaps the problem comes from another plugin and then ACF trips up.
Thanks

Elliot,
I switched to Twenty Thirteen and only have ACF activated. This is the error I get
[17-Sep-2013 13:12:29] PHP Fatal error: Call to undefined function filter_var() in /var/www/hlacharterschool.org/wp-install/wp-content/plugins/advanced-custom-fields/core/controllers/everything_fields.php on line 266

Hi @unwrittendevin
Looking at the PHP docs,
This is a function as of PHP 5.2.0
Perhaps you will need to upgrade the PHP version running on the server?
I figured out that this happens when “filter” php module is off. I turned it on and problem was fixed.
